The lake is a giant-made relic from the time of the Thassilonian empire, a monument to the vanity of RunelordKarzoug. This part of Varisia once supplied most of the stone for the countless Thassilonian cities and monuments of the ancient empire. When it finally was played out, Karzoug decreed that the Skull River should be dammed, and its waters cover the ugliest scar in his domain.[2] To this day, evidence of ancient quarrying can still be seen in many places along the shores of the lake, prompting much speculation amongst locals, as the true history of the Deep is known to very few.[3]
The most notorious inhabitant of the Storval Deep is a creature known as Black Magga, a hideous monstrosity so old, she is rumored to predate even the gods.[4]
